6. Rubik wanted a working model to help explain three-dimensional geometry.
7. It took him well over a month to work out the solution to his puzzle.
8. Rubik’s solid cube twisted and turned - and yet did not break or fall apart. Some people are still trying to work it out.
10. Over 350 million Rubik’s Cubes have been sold worldwide – making it the bestselling toy of all time.

12. With six coloured sides, 21 pieces and 54 outer surfaces, there’s a combined total of over 43 QUINTILLIOIN different possible configurations.
13. If you turned Rubik’s Cube once every second it would take you 1400 TRILLION YEARS to finish to go through all the configurations.
14. If you had started this project during the Big Bang, you still wouldn’t be done yet.
15. Yet, amazingly, the best speed cubers* can solve the cube in under six seconds.
Speed cubers = people who take part in speed cubing – a sport where competitors try and solve the cube as quickly as possible.
16. The current world record holder is Mats Valk from the Netherlands. Who completed the puzzle in 5.55 seconds.
20. This guy took a whole 25 seconds. But he was doing one-handed push-ups AT THE SAME TIME!
21. Another dude took 28.80 seconds to solve the puzzle BLINDFOLDED!
22. A three-year-old in China solved the puzzle in under two minutes.
23. And then there’s this guy, clocking in at ten minutes, using his nipple. Oh, internet.
24. Smartphone-powered Lego robots can solve Rubik’s Cube faster than humans.
26. Hell, even Mantis Shrimp can do the puzzle.
27. In 1981, You Can Do The Cube by Patrick Bossert sold 1.5m copies.
28. The first annual International Rubik’s Championships were held in 1982.
29. The winner was Minh Thai (USA) with a relatively slow (compared to modern times) solve of 22.95 seconds.
30. Every legal permutation of the Rubik’s Cube can be solved in 20 moves or less.
31. The world’s largest Rubik’s Cube is located in Knoxville, Tennessee. It is three metres tall and weighs over 500kg.
32. The smallest cube is 10mm wide and was made by Russian Evgeniy Grigoriev.
35. The most expensive cube ever produced is the Masterpiece Cube, created by Diamond Cutters International in 1995.
36. This actual size, fully-functional cube features 22.5 carats of amethyst, 34 carats of rubies and 34 carats of emeralds, all set in 18-carat gold, and has been valued at $1.5m.
